WINDOW.

SPECIFICATION forming part of Letters Patent No. 389,490, datedSeptember 11l 1888.

Application tiled March 7,1888.

To all whom t may concern:

Be it known that I, JOHN B. ZETTLER, a cltizen of the UnitedStates,residing at Cantn, in the county of Stark, State of Ohio, haveinvented certain new and useful Improvements in Windows, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to windows,and among the objects in view areto obviate the u se of balances or weights, and to provide a simple andconvenient means for raising and lowering the sashes thereof.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof be particularly pointed out in theclaims.

Referring to the drawings, Figure l is a front elevation of a windowconstructed in accordance with my invention, the upper sash being partlylowered. Fig. 2 is a vertical section on the line 'y y of Fig. 1; andFigs. 3 and 4 are front elevation and sectional views, repectively, of ameans for operating the rackars.

Similar letters of reference indicate like parts in all the figures ofthe drawings.

A represents the sides of the window-cas ing, and A A2 the upper andlower sills, respectively. Between the usual vertical dividing-strips ofthe side casings, A, are mounted for Asliding the upper and lowerwindowsashes, B B. The side rails, B2, of the upper sash, B, projectbeyond the upper transverse rail of said sash and form a screen-frame,B3, covered with suitable material, as woven wire B4. Projecting fromeach side of the upper sash into the usual weight-receiving recess, A,through vertical slots A4, formed in the inner faces of the side sashesA,'andintermedi ate the vertical dividing-strip, are lateral T- shapedarms B5, the T ends of which are secured to the sash-frames, and totheir opposite ends are secured the upper ends of depending verticalrods B, which extend down through openings A5, formed in the lower sillbelow the same and into the wall, their lower ends being secured to atransverse rod, Bl. Secured to the cross-bar B7, about midway its lengthand depending therefrom, is a rackbar, B8, and meshing therewith is ascroll- Serial No. 266,464. (No model.)

gear, B, journaled in a bracket, B10, the rackbar passing throughvertically-opposite openings Bm. Upon the shaft of the gear B0 ismounted an operating-crank, B, which pro- 5 5 jects through the wall andwithin a convenient position for turning by the hand of the operator. Byrotating the crank B, motion is imparted to the'gear B, which, throughthe medium of the rack-bar B8, cross-bar B7, and 6o vertical rods B6,raises and lowers the upper sash of the window. Vhen the upper sash islowered for ventilation,the screen B4 takes its place and prevents theentrance of dust,insects, Svc. It is also evident that the sash cannot6'5 be further lowered from the outside, but must be operated throughthe medium of the crank Bu. Vhen the sash is raised, the screen passesvertically through a vertical recess in the upperZsill, A', and into thewall. 7o

The mechanism employed for raising and lowering the lower sash issimilar to `that described, and the same consists of a rack-bar, C,depending from the lower rail of the lower sash through an openingformed in the lower sill, A2. Meshing with the rack-bar is a similarscroll-gear, C', mounted in a bracket, C2, and provided with auOperatingcrank, C. The operation of raising and lowering this sash issimilar to that of the upper sash, and it, like 8o its companion, cannotbe raised or lowered vfrom the outside, but must be' operated by themeansemployed. If desired, ordinary gears may be substituted for thescroll-gears described; but these do not possess the advantages of thelatter, as they do not form a lock against raising and lowering from theoutside; and, in fact, unless the sashcs are very light their weightalone is sufficient to cause the gears to rotate, which,of course,isundesirable. 9o Aside from this, less power is required to raise andlower the sashes through the medium of scroll-gears than with theordinary gears mentioned.

The scrollgear is mounted slightly at an angle, so that only one portionthereof is in operative connection with the raclrbar C, all as clearlyshown in Fig. 4.

Having described my invention and its operation, what I claim isl. In awindow, the combination, with a sash provided with laterally-projectingarms,
